type Histogram

type Histogram struct {
	Count          int64     `json:"count"`
	Sum            float64   `json:"sum"`
	CountPerBucket []int64   `json:"count_per_bucket"`
	Bounds         []float64 `json:"bounds"`
}

Histogram is a simple implementation of histogram expvar.Var.

`Bounds` specifies the histogram buckets as follows (length = len(bounds)):

(-inf, Bounds[i]) for i = 0
[Bounds[i-1], Bounds[i]) for 0 < i < length
[Bounds[i-1], +inf) for i = length
